Companies that supply unmanned aircraft systems for filming say they’ve seen a surge in orders after the FAA opened the way to their usage in filming, reports the Los Angeles Times.

“They are just beating down our door,” Tony Carmean, a principal in San Diego-based Aerial MOB, told the publication.

His company had received about 50 requests from TV, movie and commercial producers to use his drone equipment, the story reports. So far, his company has submitted 18 applications for drone permits to the FAA, and received approval for two.

“Most of the projects will film in Southern California early next year. Carmean said he could not identify the projects because of non-disclosure agreements,” the piece reports.

FilmL.A. has been receiving about five calls each day about using drones, but hasn’t yet issued any permits, the article notes.

The report adds: “Under the new rules, drones can be used only on sets that are closed to the public and cannot be operated at night. Operators must have private pilot certificates, keep the drones within their line of sight and below an altitude of 400 feet.”
